What are Hudson River Trading Perks + Benefits

Hudson River Trading Benefits Overview

Health Coverage
Nothing is more important to us than employee health. At HRT, you can expect company-paid (no premiums!) medical and dental coverage across our global offices. We also offer an HRT-funded Health Savings Account, affordable vision insurance, and flexible spending accounts to US employees and their dependents. Plus, a One Medical primary care membership, unlimited sick days, mental health resources, telemedicine services, and more. Similar competitive health benefits await employees at our global offices.

Family Support
Supporting our employees also means supporting the people that they love. Birthing parents receive 18-20 weeks paid parental leave, or 12 weeks for non-birthing (including adoptive and foster) parents. US employees can access family planning support through Progyny including egg freezing, fertility treatments, adoption and surrogacy benefits. Access caregiver support when you need it, including back-up child care, through our partnership with Bright Horizons. NYC parents returning to office will also find a hospital-grade pump and sterilizer for use in our wellness rooms. We offer plenty of family-friendly events including kids' day, family nights, and company-wide trips.

Meals & Snacks
We take food very seriously. HRTers enjoy complimentary breakfasts and lunches (chef-prepared in NYC and London, reimbursement or catered options elsewhere), along with a wide selection of healthy snacks. Need a caffeine boost? Our coffee bar awaits. And for moments of relaxation, a well-stocked beer and wine fridge.

Inclusive & Accessible Environment
We offer gender-affirming health coverage, gender-neutral bathrooms in many of our offices, and support for HRTers who are transitioning at work. Private wellness rooms are available for meditation, prayer, lactation, or as a private space to attend a virtual appointment. We’re always looking for ways to remove barriers and empower employees of all abilities — if there’s a way we can make it easier for individuals to do their best work, we’re here for it.

Our social calendar includes regular outings like pottery, painting, pizza making, team dinners/happy hours, and an annual volleyball tournament. We take regular team retreats and company-wide trips to connect with each other (families included!) In-office, you can find us unwinding at the end of a long day with video games, happy hours, snack drops, wine/tea club, poker, or table tennis!

Time Off
We believe recharging is important, and time off is encouraged. Employees receive generous paid vacation along with personal days, market holidays, and company-wide trips.

Enjoy an on-site cardio and weight room in NYC, complete with sweeping views that will make going to the gym even easier. And for those in our other offices, we've got you covered with fitness reimbursement. We also offer virtual group classes, so you can stay active and connected no matter where you are.

Come as you are! Our dress code is whatever makes you feel comfortable, at ease, and able to do your best work — whether that be your favorite pair of sweatpants or runway best.

Mental Health
We’ve partnered with therapists to offer free virtual counseling sessions globally for all HRTers. We also offer a Modern Health membership, which provides access to appointments with therapists and coaches for employees and their dependents at no cost.

Hybrid Work
We recognize that different work carries different in-office needs: some teams require round-the-clock coverage or hands-on maintenance, while others operate across different continents and time zones. While the majority of teams adopt a fairly even split between in-office and remote work, many choose to come in every day. To support your commute, we offer pre-tax commuter benefits.

Professional Development
Learning at HRT never stops. We offer employees reimbursement for career development courses, in-house professional learning & development opportunities, and a vibrant intellectual culture that presents daily opportunities to learn something new.

Financial Wellbeing
In addition to competitive compensation, we offer generous 401k matching to all full-time US employees, and pension matching in our EU locations. Moving to a new city to start your career at HRT? Relocation assistance is available to support your move.
